  • a spray mixture prepared from a wettable powder of the active ingredient was poured into barley plants about 8 cm high (0.006% active substance based on the volume of the earth). Care was taken to ensure that the spray mixture did not come into contact with the plant parts above ground. After 48 hours, the treated plants were dusted with conidia of the fungus. The infected barley plants were placed in a greenhouse at approx. 22 ° C. and the fungal attack was assessed after 10 days.
  • Apple cuttings with 10-20 cm long fresh shoots were sprayed with a spray mixture (0.06% active substance) made from wettable powder of the active ingredient. After 24 hours, the treated plants were infected with a conidia suspension of the fungus. The plants were then incubated for 5 days at 90-100% relative atmospheric humidity and placed in a greenhouse at 20-24 ° C. for a further 10 days. The scab infestation was assessed 15 days after infection.
  • Compounds Nos. 1.9, 1.17, 1.24, 2.17, 3.6, 3.7, 3.11, 4.50, 4.81, 4.89, 4.90, 4.91, 4.92, 5.13, 5.14, 5.36, 5.40, 5.70, 6.1 and 6.8 and others inhibited disease incidence to less than 10%. Untreated but infected shoots showed 100% Venturia infestation.
